These are exaxmples of a quantitative observation.

Measuring is the expression of an observed quantity in a number with a relevant unit that can be compared with other values of the same quantity.

It is not limited to physical quantities, but extends to a quantitative description of the whole of reality. Measurements are usually quantitative observations, and their results are expressed in

  • numerical values, and
  • units

Show that a light ray that strikes two mutually perpendicular reflecting surfaces is reflected back exactly parallel to the dire
DedPeter [7]

Take a look at the attachment below. As you can see, the figure demonstrates a 90 degree angle such that the surfaces are perpendicular, and hence are independent of the angle of incidence. You could say that this forms a part of a parallelogram -

The average speed of sound in water is 1500 m/s. how long would it take a sound wave to travel 9000 m? your answer
ryzh [129]
1500m = 1 sec

9000m/1500 = 6

So, it would take 6 sec to go 9000m

At what distance would the repulsive force between two electrons have a magnitude of 4.0 N?
borishaifa [10]

Answer:

7.6\cdot 10^{-15} m

Explanation:

The electrostatic force between two electrons is given by:

F=k\frac{e^2}{r^2}

where

k=8.99\cdot 10^9 Nm^2C^{-2} is the Coulomb's constant

e=-1.6\cdot 10^{-19}C is the electron charge

r is the distance between the two electrons

In this problem, we know F=4.0 N, so we can re-arrange the equation to calculate r:

r=\sqrt{\frac{ke^2}{F}}=\sqrt{\frac{(8.99\cdot 10^9)(-1.6\cdot 10^{-19})^2}{4.0 N}}=7.6\cdot 10^{-15} m
